ohmage is an open-source participatory sensing technology platform. It supports expressive project authoring; mobile phone-based data capture through both inquiry-based surveys and automated data capture as well as temporally and/or spatially triggered reminders, data visualization and real-time feedback; privacy respecting data management; and extensible data exploration. All captured data are automatically timestamped, geocoded and uploaded for analysis and visualization.
The ohmage app is currently available for Android (2.2+) and iOS devices. While the original ohmage app was developed for the Android platform, the ohmage team has worked closely with UCLA's Mobile Web Framework group to create a lightweight version of the app that is compatible with a broad variety of devices, including iOS devices. All versions are listed for download below.
